Abstract
A seal ring having rounded-corner rectangular shape in cross-section is mounted in a recessed groove formed in ring configuration in a pressure-contact surface of a seal jig such that major axis of the seal ring is oriented perpendicular to the pressure-contact surface and the seal ring is projected out the pressure-contact surface by about 15-35% of length of the major axis to be compressively deformable in the direction of the major axis, and stoppers formed of low thermal conductivity resin are disposed on the pressure-contact surface, the peripheral portion of the opening of an article being tested is brought into pressure-contact with the seal ring in a manner such that the stoppers are interposed therebetween and that the compressively deformed seal ring provides an adequate sealing effect to seal the opening, whereby testing may be conducted without bringing the article being tested into contact with the seal jig.
